"pinko" build a laser trigger for chronograph using PIC18F2550 and LM393 comparators. He writes: I finished this laser wall trigger for my HIGH RESOLUTION AND ACCURACY CHRONOGRAPH. The purpose of this device is to generate the trigger start and stop impulses for my chronograph as...

Silicon Lab’s TS1100 and TS1101 current sense amplifier’s features discussed in this app note. Sensing and controlling supply current flow are a fundamental requirement in most all electronic systems from battery-operated, portable equipment to mobile or fixed-platform power...

"pinko" has designed a simple datalogger based on a PIC microcontroller that logs data on a SD Card. He writes: Some time ago I decoded to make a simple general purpose Data Logger with the following parameters for the project. it should have very simple design that should be...

ikalogic.com launched "IkaScope" a new wireless oscilloscope probe that is able to make measurements directly on your mobile phone or your laptop. IkaScope transfers measured signals over high speed wifi connection and it will remember your home or office access points. It will work...

Robert Gawron tipped us with his latest build. He writes: Today I will show a very simple ionization chamber that can detect radioactivity. I was able to detect with it ionizing radiation from a smoke detector (Am241 isotope). It’s also immune to electromagnetic interference (EMI)...

In this instructable by gustavio101 you will know how to make a capacitance meter using Arduino displayed on the TM1637 display with a range from 1 uF to 2000 uF. To build this project you need the following parts: Resistors 1x: 220 Ohm 1x: 10 kOhm, 8000 Ohms also would...

In this tutorial at hackster.io you will learn how to log data from LM35 temperature sensor values to an SD card and store it as CSV file. In order to build this project you need the following parts: Arduino UNO idIoTware Shield USB-A to B Cable SD Card (up to 8GB)...

An ultrasonic parking sensor project from Ch00ftech: After electing to use the PING))) sensor exactly as directed, I needed to build the rest of my circuit.  I wanted to build something robust that would mount nicely on the wall of my dad’s garage.  Figuring that the sensor...
